Which energy sublevel is being filled by the elements Ce to Lu?
The energy sublevel being filled by the elements Ce to Lu is the 4f sublevel. These elements are part of the lanthanide series and have their outermost electrons entering the 4f orbital.
Which energy sublevel is being filled by the element K to Ca?
4s. Both K and Ca are s block and they are both in the 4th period. So in K, you have 4s1 and in Ca you have 4s2
How would you justify the presence of 18 elements in the fifth of period of periodic table?
In the fifth period of the periodic table, the atoms of the elements in the first two groups are adding 1 and 2 electrons, respectively, to their highest energy 5s sublevel. Starting in group 3/IIIB and going through group 12/IIB, the atoms of those elements are adding electrons to their highest energy 4d sublevel. Since the d sublevel can contain a maxium of 10 electrons, there are 10 elements whose atoms are filling the 4d sublevel. Once the 4d sublevel is filled, the next higher energy sublevel is the 5p sublevel. Starting with the group 13/IIIA elements, the 5p sublevel is being filled. Since a p sublevel can contain a maximum of 6 electrons, there are six elements whose atoms are filling the 5p sublevel. 5s sublevel filling: 2 elements 4d sublevel filling: 10 elements 5p sublevel filling: 6 elements --------------------------------------- Total: 18 elements For a printable periodic table that includes electron configurations, go to the following link: http://www.nist.gov/pml/data/periodic.cfm
Elements in which the d-sublevel is being filled have the properties of?
Elements in which the d-sublevel is being filled have properties such as variable oxidation states, colored compounds, and the ability to form complex ions due to the arrangement of electrons in the d orbitals. These elements typically exhibit metallic behavior and can form transition metal compounds with unique chemical and physical properties.
The outermost s and p sublevels of the representative elements are?
The outermost s sublevel of the representative elements is filled first, followed by the p sublevel. This results in the outermost electron configuration being in the s and p sublevels.
Which energy sublevel is being filled by the elements Ce to Lu?
The energy sublevel being filled by the elements Ce to Lu is the 4f sublevel. These elements are part of the lanthanide series and have their outermost electrons entering the 4f orbital.
Which energy sublevel is being filled by the elements Y-Cd?
The elements Yttrium (Y) and Cadmium (Cd) fill the 4d energy sublevel.
Which energy sublevel is being filled by the element K to Ca?
4s. Both K and Ca are s block and they are both in the 4th period. So in K, you have 4s1 and in Ca you have 4s2
Which energy sublevel is being filled by the elements Y to Cd?
The elements Y (Yttrium) to Cd (Cadmium) are filling the 4d energy sublevel. This range includes the transition metals from Yttrium (atomic number 39) to Cadmium (atomic number 48), where the 4d orbitals are progressively filled with electrons.

The outermost s sublevel of the representative elements is filled first, followed by the p sublevel. This results in the outermost electron configuration being in the s and p sublevels.
Energy-favorable states for the d sublevel are when it contain electrons?
Energy-favorable states for the d sublevel occur when it is half-filled or fully-filled with electrons. This is because half-filled and fully-filled d sublevels have lower overall energy due to electron-electron repulsions being minimized. Additionally, these configurations result in greater stability and lower energy.
Why aren't there any p-block elements in the first period of the periodic table?
Because in the first period, only the first energy level is being filled with electrons, which can take only a maximum of 2 electrons in the s sublevel. The electron configuration of hydrogen is 1s1 and helium is 1s2. There is no p sublevel in the first energy level.
The Aufbau principle states that an electron?
The Aufbau principle states that electrons must be added to elements and ions in a VERY specific order with the lowest energy level being filled first and the highest last. This is where the Aufbau triangle comes in. It shows the order in which the energy levels must be filled.
Why is copper a transition metal as it have completely filled d sub-shell?
An electron moves from the 4s sublevel to produce a completely filled 3d sublevel. A completely filled sublevel is more stable. Just because it has a filled d sublevel doesn't prevent it from being a transition metal. It has variable valence (1+ and 2+).
When do D orbitals start gettin filled?
D orbitals start to get filled after the 3p orbitals in the periodic table. They are typically filled after filling the 4s orbital, as the 3d orbitals are the next to be filled in the transition metal series.
